It's the west end of Toronto, the apartments are small, and everybody is 27 and making some kind of art. In the wake of her mother’s death, Sophie pays rent by making stained glass mosaics for rich people and plays house with her childhood friend and sometimes-lover, the beautiful boy Alex. Both are from Newfoundland but move easily in this world of crowded patios and DIY movie shoots. When Sophie meets the glamorous poet Maggie, who is the downtown product of a hundred cool queer bars, she falls into a bewildered infatuation, but secrets emerge that threaten to crumble the foundation of her relationship with Alex and Maggie both. Moving from bohemian Toronto to an arts colony in a castle in France and then back to Newfoundland, Mudflowers examines the impact of family that one is born into and family one chooses, exploring new and unconventional intimacies.
